Tuning the glass micro-structure for controllable Bi0/Bi+ ions to promote efficient Ho3+ fluorescence
Bi ions with a wealth of chemical states can experience a chemical-state evolution by engineering the glass structure to manipulate its final chemical state. In this work, efficient enhancement of Ho3+ emission is observed with the change of local glass environment around Bi by adding Al2O3 in the m...

Correction: Covalent layer-by-layer films: chemistry, design, and multidisciplinary applications
Correction for ‘Covalent layer-by-layer films: chemistry, design, and multidisciplinary applications’ by Qi An et al., Chem. Soc. Rev., 2018, DOI: 10.1039/c7cs00406k....

Silkworm silk-based materials and devices generated using bio-nanotechnology
Silks are natural fibrous protein polymers that are spun by silkworms and spiders. Among silk variants, there has been increasing interest devoted to the silkworm silk of B. mori, due to its availability in large quantities along with its unique material properties. Silk fibroin can be extracted fro...

Influence of surfactants of different nature and chain length on the morphology, thermal stability and sheet resistance of graphene
The effects of surfactants of different nature (anionic, cationic and non-ionic) and chain length on the morphology, microstructure, thermal stability and electrical resistivity of liquid exfoliated graphene (G) were investigated. Microscopic (SEM and AFM) observations revealed that the thickness of...

Influence of long-range forces and capillarity on the function of underwater superoleophobic wrinkled surfaces
Underwater superoleophobic surfaces can be considered a particular type of lubricant-infused surface, that have anti-fouling properties by virtue of a trapped water layer that repels oils. However, as their function relies on a water layer being trapped in the surface roughness, it is crucial to und...

Reviving lithium cobalt oxide-based lithium secondary batteries-toward a higher energy density
By breaking through the energy density limits step-by-step, the use of lithium cobalt oxide-based Li-ion batteries (LCO-based LIBs) has led to the unprecedented success of consumer electronics over the past 27 years. Recently, strong demands for the quick renewal of the properties of electronic prod...

First-principles calculations of oxidation potentials of electrolytes in lithium–sulfur batteries and their variations with changes in environment
Oxidation potentials of electrolyte molecules in Li–sulfur (Li/S) batteries and their variations in various solvent environments are investigated using first-principles calculations in order to understand oxidative decomposition reactions of electrolytes for cathode passivation. Electrolyte solvents...

A viable strategy for screening the effects of glycan heterogeneity on target organ adhesion and biodistribution in live mice
This work represents the first broad study of testing diverse heterogenous glycoconjugates (7 different glycoalbumins) for their differential in vivo binding (11 different cancer cell types) in both cell- and animal-based studies. As a result, various changes in biodistribution, excretion, and even ...

Electromagnetic Interference (EMI) shielding performance of lightweight Metal decorated Carbon nanostructures dispersed Polyvinylidene fluoride flexible films
We report electromagnetic interference shielding of metals decorated MWCNT/rGO in polyvinylidene fluoride (PVDF) flexible films. X-ray diffraction patterns show the presence of metallic nanoparticles firmly bound with carbon fillers of the composite. The morphological studies proved the homogeneous ...

The discovery of a freezing-induced peptide ligation during the total chemical synthesis of human interferon-?
A counterintuitive freezing-induced peptide ligation was discovered in the total synthesis of human interferon-ε (hIFN-ε) which blocks HIV infection through unique mechanisms. The successful synthesis of hIFN-ε (187 amino acids) in this research laid the foundation for related anti-AIDS drug develop...

A Flexible Ionic Synaptic Device and Diode-based Aqueous Ion Sensor Utilizing Asymmetric Polyelectrolyte Distribution
This work developed an ionic diode of high rectification ratio with simple device structure and readily fabrication process by utilizing asymmetric polyelectrolyte distribution. Detection of aqueous ions was demonstrated by applying the diode as pH sensor. Two terminal ionic synaptic devices utilizi...

CTAB-assisted size controlled synthesis of SAPO-34 and its contribution toward MTO performance
SAPO-34 shows higher light olefin selectivity in the reaction of methanol to olefin (MTO), but its small pore system implies diffusion limitation to bigger molecular products and results in coking too. To inhibit these limitations, sub-micrometric size SAPO-34 crystallites were successfully synthesi...

Origin of Fast Oxide Ion Diffusion along Grain Boundaries in Sr-doped LaMnO3
The prospect of significantly enhanced oxide ion diffusion along grain boundaries in Sr-doped LaMnO3 (LSM) was investigated by means of density functional theory calculations applied to a Σ5 (3 1 0)[0 0 1] grain boundary. The structure of the grain boundary was optimized by rigid body translation, a...
